应用空心包体式三轴应变计,采用钻孔应力解除法系统地对淮南矿区现有主采煤层进行地应力现场实测,得到不同位置和埋深的实测地应力数据。通过对实测数据的系统分析,得出矿区范围内地应力场的分布规律。 By using the hollow inclusion body triaxial strain gauge, the ground stress of the existing main coal seam in Huainan mining area was systematically measured by drilling stress relieving method, and the measured geostress data of different positions and depths were obtained. Through the systematic analysis of the measured data, the distribution law of the in-situ stress field in the mining area is obtained.
